Optical recognition LED control

I probably shouldn’t find this as worthy as I do. It’s the optical recognition equivalent of wiring up a LED to a switch,, but it just appeals to me. [Ashish], one of our favorite optical recognition hackers of late, sent along this product of his boredom. If only he’d give us some source and a wiring diagram…

This is an interesting hack. Sure, it’s not new, but it’s a new (it might have been done before, but I haven’t seen it) mix of old hacks. I like it. :D Thumbs up for the work and I’d like to see what people do with this in the future.

@1: Okay, so what if you did it before, as far as I can see this site exists to highlight people that have done something and taken the time to make the information available (okay so this one could do with more detail), did you post your info somewhere when you were finished so beginners like me could get inspiration and information from it?I love this site, it’s the smaller hacks that help me to understand what will be possible when I’ve finished learning my uC programming and give me an idea of how much can be accomplished within reason.

My technically inept roommate felt the video required some sort of stability type device. Perhaps said hacker could have ‘hacked’ a tripod first.I took issue with mixing country music with hacker video.Otherwise, nice programming.

I agree about the shaky one-handed camera but if you are trying to show multiple objects in close-up and don’t have a cameraman it’s difficult. The earlier posts on his blog are mostly in a similar vein, combining a couple of simple hacks to make a neat device. the laser gesture-control coupled to a serial port relay for controlling electrical items is a neat hack that I’d like to try.

No matter what hobby/special interest website I go to there is always an unfortunate group of people who seem to be compelled to criticize someone else. Some of the above posts reflect highly evolved egos. I agree with the comment made by Phil. If you had done something like this in the past but did not take the time to create a video record of the event, your experience is irrelevant to us. The community would be better served if, instead of announcing your superiority to the world, you recreated your work and supplied us with a video record. In other words, put up or shut up!

well the problem with people dedicated to criticizing is, that here is a lack of such people. it’s plainly stupid just to say “ah, nice hack, cool *wankwank*”. That’s boring. to bring up a discussion it needs pros and cons and some people here feel dedicated to providing cons. what else reason serves this comments page if not to discuss?

I have seen applications similar to this in the past that are being used for office personal recognition systems. In one example the LED controller detects where the subject is located and which way he or she is facing. I believe the system I am referring to was designed by Lunar Accents Design ( http://www.LunarAccents.com ). I have also seen other LED control systems in the airport which detect the movement of passengers going through the metal detectors.
